RNLS Male Elbow (BSPT/NPT) fittings are made of 316L stainless steel for corrosion resistance, Male Elbow push on fitting is designed to connect tube on one end, male thread(BSPT/NPT thread) connection on the other end. Sealing and locking the tube by tightening the nut. Tube O.D is available in metric size 4mm to 16mm, inch size 1/8" to 1/2". Thread sizes are available in BSPP, BSPT, NPT 1/8'' to BSPP, BSPT, NPT 1/2''. Ruisen stainless steel fittings are Food Grade,Comply to FDA Standard.
在高负荷条件下疲劳裂纹在焊接部和下板上破裂。在扩大、焊接断裂、中、低载荷条件下,裂纹在下板内扩展,在扩展方向基本平行的板厚方向上,2 mm厚的下板发生断裂?试验片所受载荷较低时,裂宁波不锈钢卡套接头纹沿晶界的扩散率、扩展区面积大、瞬断面积小、扩链区第 一阶段时间长、疲劳纹宽大、瞬断区韧性深;当试验片承受的载荷较高时,裂缝位于PSB内的萌、扩展区域面积小、瞬截面积大、扩张区第二段时间长、疲劳条纹宽度小。瞬断场坚韧的窝很浅,疲劳裂纹的初期传播方向相对于应力轴呈45°的角度,下一阶段慈溪不锈钢快拧接头变化的垂直(Vertical)应力轴产生的裂纹初期的扩展速度第2段较慢。在其扩展的初期,有在破面没有的疲劳带。在第二阶段破面有特别的特征征的疲劳之岛.关键词:不锈钢车身;激光焊接;焊线能量;与接头疲劳性能吉有缘的大学硕士学位论本文是二征和技术的关键。
